I have the ionic version 2.0.0-beta.30
when I serve my project I get this error

Caught exception:
Error: watch node_modules/angular2/src/animate/css_animation_options.js ENOSPC

Caught exception:

and many other errors like that. Can I anyone help me to solve this problem

If you’re running on Windows make sure you are running the command prompt as Asministrator (right click shortcut then select ‘Run as Administrator’)

could you share your node and npm version? It might be out of date as well.
